Researcher Exploits 18-Year-Old Design Flaw To Compromise X86 Chips

Posted by samzenpus on from the protect-ya-neck dept.

jfruh writes: Security researcher Christopher Domas has demonstrated a method of installing a rootkit in a PC's firmware that exploits a feature built into every x86 chip manufactured since 1997. The rootkit infects the processor's System Management Mode, and could be used to wipe the UEFI or even to re-infect the OS after a clean install. Protection features like Secure Boot wouldnt help, because they too rely on the SMM to be secure.
